Flashcard: KE & PE

Front

What is Potential Energy?

Back

Potential Energy is the stored energy in an object due to its position or state.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object due to its motion.

Front

How does speed affect Kinetic Energy?

Back

The faster an object moves, the more kinetic energy it has.

Front

What is the formula for Gravitational Potential Energy (GPE)?

Back

GPE = mass (kg) × gravity (9.8 m/s²) × height (m).

Front

Calculate the GPE of a 60 N basketball held 2 m above the ground.

Back

GPE = 60 N × 2 m = 120 J.

Front

What is the formula for Kinetic Energy (KE)?

Back

KE = 1/2 × mass (kg) × velocity² (m/s).

Front

Calculate the Kinetic Energy of an 8 kg ball rolling at 10 m/s.

Back

KE = 1/2 × 8 kg × (10 m/s)² = 400 J.

Front

What type of energy is associated with an object at rest?

Back

Potential Energy.

Front

What type of energy is associated with a moving object?

Back

Kinetic Energy.

Front

If an object is lifted higher, what happens to its Potential Energy?

Back

Its Potential Energy increases.
